For five days at Epcot in 1999 and for an equally short time in Castaway Cay, guests from around the world had the chance to meet with one of the largest accomplishments in audio animatronic technology: the DRU-1 (Dolphin Robotics Unit). Created by Edge Innovations in partnership with Walt Disney Imagineering, DRU-1 wowed the crowds but was ultimately decided to not have the potential of being an every-day attraction in the theme parks.
